The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Norman, OK wrote its last area forecast discussion before this special weather statement went out at Jun 26, 2:38 PM CDT, 3 hours 35 minutes earlier.
Area forecast discussion, Jun 26, 2:38 PM CDT, 3 hours 35 minutes before
Area Forecast Discussion National Weather Service Norman OK 238 PM CDT SUN JUN 26 2016 .DISCUSSION... Daily convection will be main concern with some severe weather and potential flooding the main impacts moving forward. Next couple of days weak sfc boundary(s), outflow boundaries and weak upper support will be sufficient for scattered convection. Best chance today will be near low level boundary across northern Oklahoma. A secondary area could be in southwest OK and north TX as upper low cont to spin across west Texas. This weak sfc boundary still appears to be present on Monday, a bit farther south, and will once again act as a focus for convective development throughout the day. Current atmosphere is one with plenty of instability but very little, if any shear. So storms will be slow-moving and efficient rain producers. So heavy rainfall and wind will be main concerns with a secondary hail threat. As we move forward through the work week, we see upper ridge shift back westward and northwest flow develop across the Southern Plains. This will likely lead to nearly daily chances for storms across the area. Although some severe risk will be present, main concern may turn into a water issue, in the form of flooding. Still a bit early to determine exactly where the greatest threat may end up occurring. However, currently would appear northeast half of Oklahoma would be most likely area to see multiple rounds of heavy rainfall. && .PRELIMINARY POINT TEMPS/POPS...
